CONCRETE-FORM STAY.

Application filed; September 15, 1924. Serial No. 737,756.

To all whom it may concern.

Be it known that PAUL F. RAMM, a citi- Zen of the United States, residing at Oak land, in the county of Alameda and State of California, has invented certain new and useful Improvements in Concrete-Form Stays, of which the following is a specification.

This invention relates to improvements in concrete form stays, and has for its object the construction of a device whereby the two sides of a concrete form are held in spaced relation against collapsing and bulging.

Another object is to provide a .stay which consists of two interlocking members, so formed that there is no side movement thereof when the stay is in position.

In the annexed drawing in which my invention is illustrated:

Figure 1 is a perspective view 015 a section of concrete mold, and with my improved stay in position thereon.

Figure 2 is a plan view of my stay.

Figure 3 is a fragmentary perspective View of one of the stay members.

Figure 4 is a fragmentary perspective view of the other stay member.

Referring to corresponding parts in the several views by the same numerals of reference, 1 denotes the upright studs, on the inside of which is attached the sheathing 2, this sheathing being spaced apart a distance equal to the thickness of the concrete wall. To maintain this distance between the sheathing it is usual to provide a compression member between the two portions of the form and to pass wires around the studs,

and by twisting the same to draw the two sides of the mold against the compression 4H member. With m improved stays both the wires and compression members are elimi-- nated.

These stays consist of two members 3 and 4, joined in the center as at 5 in order to facilitate handling and driving. The member 4: consists of a shank 6 formed in any desired length and provided with a bent end portion 7, which is sharpened and adapted to be driven into the stud 1. The oppo site end of the shank 6 is bent into a plane at a right angle to the end 7 to form a loop as at 8.

The member 3 consists of a shank 9, bent at the outer end as at 10 into a staple to drive into the stud. The opposite end of the shank 9 is bent downwardly at right angles, as at 11, in the same plane as the staple end 10, and a closed hook is formed on the end thereof, as at 12, to prevent removal of the 6 bent end 11 from the loop 8.

The upper face of this hook bears against the loop 8, thus preventing any side movement of the stay when in osition.

Having described my invention, I claim:

A form stay comprising two members, the ends of one of said members being bent to form a loop, one end of the other member is bent at an angle to said member, a hook formed on the end of said bend, the upper face of said hook being adapted to engage said loop, and angular bent hooks formed on the free end of said members.

In testimony whereof I aflix my signature.

PAUL F. RAMM.
